Abstract
The utility model discloses a rotating mechanism, which comprises a rotary platform, a rotary support, a rotary joint, and a speed reducer, wherein the center of the rotary platform is provided with a through hole, and the rotary joint is arranged in the through hole; the rotary support is composed of an inner and an outer rings, and a rolling body is arranged between the inner and the outer rings; the inner ring is a ring gear, and is fixedly connected with the rotary platform; the end part of an output shaft of the speed reducer is provided with a gear, and the gear is meshed with the inner ring. The structure is characterized in that a rotary seat is arranged under the rotary support, and the rotary seat is composed of an upper and a lower panels, and a circle which connects the upper and the lower panels; the outer ring is fixed on the upper panel, and the speed reducer is arranged under the lower panel; the output shaft faces upwards and is vertical to the upper and the lower panels, and the corresponding position of the upper and the lower panels is provided with an eccentric hole; the output shaft is extended into the inner ring after penetrating through the eccentric hole. The rotary mechanism has the advantages of simple structure and easy installation, and is suitable for being installed on engineering machines of excavators, cranes, etc., which can enable an operation device to revolve at the circumferential direction.
Description
(1) technical field
The utility model relates to a kind of fluid drive mechanism.Be the hydraulic gyration mechanism on excavator, hoist and so on the engineering machinery specifically, be applicable to apparatus for work revolution in a circumferential direction.
(2) background technique
As everyone knows, can on any direction at 360 degree angles, excavate or hoisting operation, swirl gear all is installed on excavator and the hoist for making equipment.This swirl gear is made of revolving dial, pivoting support, swivel coupling and speed reducer.Revolving dial center wherein is processed with through hole, and swivel coupling is fixed in this through hole.Said pivoting support contains inside and outside circle, between the inside and outside circle rolling element is arranged.Said inner ring is a ring gear, and it is fixed on the frame of excavator or hoist.The outer ring then with between revolving dial is connected mutually.Said speed reducer is fixed on above the revolving dial, and its output shaft stretches in the inner ring towards the below and after passing revolving dial.The end of speed reducer output shaft is equipped with gear, and this gear can rotate also with between inner ring around speed reducer output shaft and be meshed.Drive the speed reducer output shaft rotation by power mechanism during work, gear and the inner ring by the speed reducer output shaft end drives the revolving dial rotation again.Because equipment is installed on the revolving dial, drives the rotation of equipment by the rotation of revolving dial, thereby realized that equipment all can carry out digging operation on the either direction at 360 degree angles.
All be installed in excavator on the revolving dial for motor, oil hydraulic pump and control valve and most of hydraulic pipe line, because wherein hydraulic pipe line rotates with revolving dial during digging operation, it is feasible adopting above-mentioned swirl gear.And all be installed in the excavator of internal body for motor, oil hydraulic pump and control valve and most of hydraulic pipe line, because control valve is in the body, if adopt above-mentioned swirl gear, it is that stator terminal is connected that control valve needs by the oil pipe and the lower end of swivel coupling, and is that rotor-end needs join by oil pipe and speed reducer on the swivel coupling.Not only increased hydraulic pipe line quantity, be unfavorable for the protection of pipeline, and increased the oil duct quantity of swivel coupling inside, make the structure more complicated, install the comparison difficulty.
(3) model utility content
The technical problems to be solved in the utility model provides a kind of swirl gear, this swirl gear, simple in structure, easy installation.
For addressing the above problem, the utility model is taked following technological scheme:
Swirl gear of the present utility model comprises revolving dial, pivoting support, swivel coupling and speed reducer, and there is through hole at the revolving dial center, and swivel coupling is installed in this through hole.Said pivoting support is made up of inside and outside circle, between inside and outside circle rolling element is arranged.Inner ring wherein is a ring gear, its with revolving dial between be connected mutually.The output shaft end of speed reducer has gear, and this gear is meshed with inner ring.Its structural feature is panoramatic head to be arranged below the pivoting support, and this panoramatic head is made of with the circle that is connected upper and lower panel upper and lower panel.Said outer ring is fixed in the above on the plate.Said speed reducer is installed in below the lower panel, and its output shaft is towards the top and perpendicular with upper and lower panel.There is eccentric opening the corresponding part of upper and lower panel, and speed reducer output shaft stretches in the inner ring after passing this eccentric opening.
Take such scheme, have the following advantages:
Because its pivoting support of swirl gear of the present utility model is to be provided with panoramatic head below its inside and outside circle, this panoramatic head is fixed on the body of excavator.Panoramatic head wherein is made of with the circle that is connected upper and lower panel upper and lower panel.Said speed reducer is installed in below the panoramatic head, and its output shaft is towards the top and perpendicular with upper and lower panel.Not only the oil pipe between control valve and the speed reducer need not pass through swivel coupling, also can reduce the asphalt channel of swivel coupling, makes relatively simple for structure, easy installation.
(4) description of drawings
Accompanying drawing is a swirl gear schematic representation of the present utility model.
(5) embodiment
As shown in drawings, swirl gear of the present utility model comprises panoramatic head, pivoting support and revolving dial 5, and this panoramatic head, pivoting support and revolving dial are from bottom to top to be arranged successively.Panoramatic head wherein contains circle 3, and the upper and lower end of this circle is welded with upper and lower panel 1 and 2 respectively, is fixed on the frame of excavator by bolt 4 around the lower panel 2.Said pivoting support contains inner ring 6 and outer ring 10, and outer ring 10 wherein is fixed on the top plate 1 of pivoting support by bolt 4.Said inner ring 6 is a ring gear, is provided with rolling element 9 between itself and the outer ring 10, and it can rotate with respect to outer ring 10 by this rolling element.Rolling element wherein is a bearing.Be fixed on the upper end of inner ring 6 around the revolving dial 5 by bolt 4.
All be processed with center hole on the top plate 1 of panoramatic head, lower panel 2 and the revolving dial 5, swivel coupling 7 is fixed in this center hole by bolt 4.The stator of swivel coupling 7, rotor-end are stretched out respectively below under the plate 2 and on the revolving dial 5.Be provided with speed reducer 11 below the lower panel 2, the output shaft of this speed reducer is towards the top and perpendicular with upper and lower panel 1 and 2.Upper and lower panel 1 and 2 corresponding part all are processed with eccentric opening, and the output shaft of speed reducer 11 stretches in the inner ring 6 after the below of lower panel 2 is passed eccentric opening on upper and lower panel 2 and 1 successively.The output shaft end of speed reducer 11 is equipped with gear 8, and this gear is meshed with inner ring 6.During work, drive inner ring 6 by speed reducer 11 rotations and reach revolving dials 5 rotations that link to each other with inner ring 6.
